Patent FR-2228664-A1 (FR)
IPC: B64C39/02
Filed: 1974-05-06
Abstract: A balanced set of wings extend horizontally from a large lifting balloon chamber containing a lighter-than-air gas, such as helium. The gas is stored within eight preformed balloonettes disposed within corresponding segments of the spherical balloonette-containing chamber of sheet material distended into substantially spherical form by a slight positive air pressure. The wings are mounted on horizontal spars connected to the center of a vertical mast installed within the balloon chamber. The spars are secured against upward and downward forces by guy wires, from the mast, between which the balloonettes are disposed. External guy wires also support the wings. Rotatable couplings connect the wings to the spars to permit adjustment of their angle of attack. Turboprop engines are mounted on the wings to rotate the wings and attached chamber about its vertical axis at a relatively slow rotational, appreciable tangential speed. A control individually or collectively varies the effective angle of attack of the wings to either provide a strong dynamic lifting force for augmenting the static force of the balloons to lift large weights or to provide a strong negative dynamic lift for overcoming the static lift and manuevering the aircraft towards the ground. The control can also cyclically vary the angle of attack to tilt the top of the aircraft in a particular direction whereby the aircraft is caused to move in that direction. The control is derived from a cab hanging on a swivel joint below the mast which is stabilized to prevent it from rotating with the aircraft. This cab may be adapted from a helicopter fuselage less the rotors. Appreciable tangential speed of the wings which slowly rotate in a large diameter circle provides a strong dynamic force which is capable of lifting extremely heavy weights, such as 100,000 lbs. In conjunction with a static balloon lift component of about 40,000 or 50,000 lbs. The excess of dynamic over static lift permits the highly buoyant aircraft to be maneuvered towards the ground without requiring any ballast.

Title: Measuring the number of turns imparted by false twisting - shrinkage determined by yarn speed being used as control
Inventor: ANAHARA MEIJI
IPC: D02G1/08
Filed: 1975-02-25
Abstract: To determine the approximate number of turns imparted to a thermoplastic yarn of synthetic fibres by false twisting as it runs under the action of heat and possibly stretching through feed rollers, a false twister, and draw rollers, the speed of the yarn under normal operating conditions is measured between the feed rollers and the false twister, and is compared with that of a yarn running under the same conditions, but without false twisting. From these figures, the actual contraction in the length of the yarn can be ascertained, and on the basis of an already determined relationship for the yarn in question, between the number of turns and the amount of shrinkage, the actual degree of false twisting can be verified. A yarn speed meter may be used to put out a signal to a comparator in which a nominal value has been registered, so that when a predetermined tolerance is exceeded, the degree of false twisting is adjusted to suit. The number of turns can be counted accurately without interruption of the operation and without any harmful effect on the yarn.

Title: Bicycle frame mfg. process - uses junction pieces fitting inside tubes and fork in one piece
IPC: B62K19/18
Filed: 1975-11-14
Abstract: The manufacturing process is for racing and other bicycle frames, and instead of fitting the tubes in the junction pieces, the latter are fitted inside the tubes. The fork is in one piece. Frames for tandem bicycles can be collapsible. The junction pieces can be so fitted inside the tubes as to avoid any swellings in the latter. For tandem bicycles, the effort to operate the rear brake can be reduced by the mounting of a transmission lever at the base of the diagonal frame tube. Where the frame is in two parts, they can be secured together by conical couplings, locked in engagement by tightening a screw clamp.
